(1). In the past, when I used a solver without a post processor, the FIELDVIEW was the one for 3-D flow field presentation. It is flexible and can do almost everything I wanted to do. (2). For 2-D plotting, and charting, the TECPLOT was used instead of the FIELD VIEW. (3). So, these two codes were used at the same time to do the post-processing. (4). For solvers with integrated graphic processor, it is convenient to use the integrated processor, even though it may not have all the power and features. (5). There are other processors you can use, and I think, it depends on the organization which determines the code you use and the type of problems you are trying to solve. I can only say that the above two codes are good codes for me in the past.
